A woman, who lured her own sister home by text before brutally stabbing her 68 times in a frenzied knife attack so she could steal her husband, has been jailed for life..

The accused 27 year old Sabah Khan, was jailed for life after murdering mum-of-four Saima Khan at the family home in Luton, Bedfordshire, while her children slept upstairs.

She pleaded guilty at the Old Bailey on Monday and shocking details of the horrific killing emerged as she was handed a life sentence, with a minimum of 22 years.

The court heard Khan was having an affair with Saima’s taxi driver husband Hafeez Rehman.

The 34-year-old was with the sisters’ parents at a local mosque attending a late night funeral at the time of the attack on May 23, last year.

Khan had been caring for her two nieces, aged seven and one, and nephews aged four and two, when she text her sister, who was at work, saying she needed to come home quickly as her children were crying.

The Old Bailey was told that even after Saima had died, evidence was found to show that the younger sister had pulled away at clothing to inflict more deep knife wounds.

Sabah Khan appeared for sentencing having pleaded guilty earlier last week to the murder of her sister.

She was dressed in a black jacket and trousers as she listened to the facts given by the prosecution.

Prosecutor Jane Bickerstaff QC told the court that living at the house was Sabah Khan, her sister Saima and her husband Hafeez Rehman, along with their four young children.

Also under the same roof was the sisters’ elderly parents and another brother.

Miss Bickerstaff told the court that Sabah Khan “had been in a sexual relationship” with her sister’s husband Hafeez.

The prosecutor told how, on May 23 last year, an elderly relative of the family died and it was arranged that the parents, along with Hafeez Rehman, would attend the funeral at a local mosque.

Saima was unable to go because she had to attend the home of an elderly woman in her role as a carer that night.

Sabah also remained at home to look after her sister’s four young children – a seven-year-old daughter, two sons aged four and two and a baby girl, who had just had her first birthday.

Miss Bickerstaff said Saima left the house at around 10.15 that night to go to work but, half an hour later, Sabah Khan texted her sister to say that one of the children was crying and she should come home quickly.
